AIX - Hardware Installation and Configuration Management

AIX - Hardware Installation and Configuration Management

Available hardware platforms: MCA-based uni-processor models (rs6k), MCA-based symmetric multiprocessor models (rs6ksmp), ISA-bus models (rspc), PCI-bus models (CHRP). AIX V5.2 is not supported on MCA and PReP architecture hardware. The "AIX Statement of Direction" gives a complete list of unsupported models.

lscfg

Displays configuration, diagnostic and VPD information about the system.
lscfg -vp : Displays the system model, machine serial, processor type, number of processors, processor clock speed, cpu type, total memory size, network information, filesystem information, paging space information, and devices information.
lscfg | grep proc | wc -l : lists the # of processors.


prtconf or lsconf

Displays system configuration information.
prtconf -s : displays the processor clock speed.
prtconf -k : displays the kernel type in use.
prtconf -m : displays memory.

snap

Gathers system configuration information.
snap -a : gathers system configuration information. The output is written to the /tmp/ibmsupt directory.

uname

Displays the name of the current operating system.
uname -a : displays the machine ID and version banner.
uname -x : displays the operating system in use, the host name, the machine ID number of the hardware, the release number of the operating system, the operating system version and the system model name.

mach

Displays the processor architecture of the machine.

getconf

Displays system configuration variable values.
getconf HARDWARE_BITMODE : displays hardware bit mode (64 or 32 bit).
getconf KERNEL_BITMODE : displays kernel bit mode (64 or 32 bit).
getconf DISK_SIZE /dev/hdisk2 : displays disk size in MB.
getconf REAL_MEMORY : displays real memory size in MB.

cfg2html

A system configuration to HTML converter (Open Source)


file


Determines the file type.
file prog : displays user process bit mode of program prog. Returns:
executable (RISC System/6000) or object module not stripped (32 bit program),
or 64-bit XCOFF executable or object module not stripped (64 bit program).
file /unix : the returned link shows which kernel is running: unix_up = 32-bit uniprocessor kernel, unix_mp = 32-bit multiprocesssor kernel, unix_64 = 64-bit multiprocessor kernel.

cfgmgr

Configures devices by running the programs in /etc/methods directory and optionally installs device software.
cfgmgr : runs the Phase 2 configuration rules (second boot phase for normal boot) (same as using the -s flag).
cfgmgr -v : makes devices available that where not powered on when the system started.
cfgmgr -l scsi1 : configures detected devices attached to the scsi1 adapter.
cfgmgr -i /usr/sys/inst.images : installs device software (using the directory /usr/sys/inst.images) automatically during configuration.

chcons

Redirects the system console to device or file, effective next startup.
chcons -a login=enable /dev/tty0 : changes the system console to device /dev/tty0. Use /dev/lft0 for the default LFT display.
chcons /tmp/console.out : redirects the system console to file /tmp/console.out.

lsdisp

Lists the displays and the default display currently available on the system.

chdisp

Changes the display used by the LFT subsystem.
chdisp -p gda1 : changes the default display permanently to gda1.


lsattr

Displays attribute characteristics and possible values of attributes for devices in the system.
lsattr -EHl sys0l sys0 : displays system attributes (realmem ...)
lsattr -EHl proc0 : displays the state, type and frequency of processor proc0.
lsattr -El rmt0 : lists the current attribute values for the tape device rmt0.
lsattr -El tty0 -a speed : lists the current value of the speed attribute for serial port tty0.


lsdev

Displays devices in the system and their characteristics.
Examples:
lsdev -P -H : lists the Predefined (supported) Devices (in the PdDv object class).
lsdev -C -H : lists the Customized (configured/defined) Devices (in the CuDv object class).
lsdev -C -c disk : lists all the PVs (class disk) in the system along with the status and location code.

listdgrp

Displays devices in a device class.
listdgrp disk : list the devices in the disk class.

getdev

Lists devices that match the specified criteria.
getdev type=proc_rspc : lists all devices of type proc_rspc.

getdgrp

Lists device classes that match the specified criteria.
getdgrp : display all device classes.

chdev

Changes a device's characteristics.
chdev -l hdisk2 -a pv=yes : assigns a PVID to hdisk2.


mkdev


Adds a device to the system.
mkdev -l hdisk2 : make the already defined disk device hdisk2 available to use.
mkdev -l hdisk1 -a pv=yes : makes an available disk a PV (assigning a PVID), if it does not already have one.
mkdev -c tty -t tty -s rs232 -p sa0 -w s1 -a login=enable -a term=ibm3151 : adds an ibm3151 RS232 terminal using adapter sa0 port s1 with login enabled.


rmdev

Removes a device from the system.
rmdev -l tty0 -d : removes the tty0 device definition from the CuDv object class (ODM).
rmdev -l hdisk1 : unconfigures PV hdisk1 and changes its state from available to defined (definition is not removed from the CuDv object class (ODM).
